Answer:
8.46
Step-by-step explanation:
Percent means 1 hundred. If you want to find out what 43.9 out of 100 is, the answer is right there (43.9%). However, if you were given lets say, 27 out of 30 and you wanted to find what percent it is. You would do 27 divided by 30 and then multiply by 100. So the answer for that would be 90%
So yeah, 43.9 out of 100 is 43.9 percent. Hope this helped!

1.5/8=0.1875 divide by the original amount
0.1875*100=18.75 find the percentage
